LEFT OR RIGHT
Special Tools Required
 00 9 316
 00 9 317
Installation:
Carefully lever out trim ➀ with special tool 00 9 317.
Fit trim ➀, raise sealing lip ➁ with special tool 00 9 316 and at same time snap trim ➀ into place.

special tool xx316 appears to be a plastic trim tool.
xx317 seems to be a small flat blade 'awl' (think screw driver but doesn't get wider; a small enough screw driver should work.

The picture is terrible of the holding clip but there are a BUNCH of clips that look like they clip straight in to the car, it looks like it pulls straight away and pushes straight toward, the trick being to install the new one, you need to pull the rubber seal out of the way as you do each clip.

Excellent post ! Mine always tends to come out loose when I use the PW. Figured the retention tab on the plastic was just fatigued and I needed to reseat the trim. Going to try the nip-tuck per the last post

I've never pulled it out to see how it's held. I presumed it was plastic tabs on the trim that clipped it. It came loose one day when I hit it on the right angle with the pressure washer. Every once in awhile it comes ajaw when I pressure wash the car....and I just press it back it. I suppose it needs that rubber outlined in the post pulled so it can properly seat
